Florida Approved Wall Panels, Drip Stop Metal Roofing, and Widest Builds

This week the Pole Barn Guru discusses reader concerns about Florida approved board and batten panels for walls, the use of drip stop or condenstop in residential applications, and what the widest build without support poles could be.

Close up image of Florida on a map with a pin over Tampa.DEAR POLE BARN GURU: I need a 4×8 siding material that has a Florida Product Approval Code. I was hoping to use Georgia-Pacific Plytanium T1-11, but it does not seem to be approved. What would you suggest for a board-and-batten siding that is approved? The barn is 30×48, 14′ side walls. CHRIS in ORLANDO

DEAR CHRIS: Plytanium is not a structural panel, however it could be applied as siding over an approved OSB or plywood sheathing.

JamesHardie Cempanel siding (as an example) has a Florida approval (FL13223). You can stop at your local The Home Depot ProDesk and inquire as to what other readily available options would have Florida approvals.

 

DEAR POLE BARN GURU: Hello, my name is Martin and I am a local building inspector here in Ohio. I do residential and commercial building inspections. I recently inspected a newly built home that had Drip Stop metal installed on the roof. It was installed on 2×4 trusses 2’ on center with pine 2×4 purlins. This new build home has NO plywood or moisture barrier other than the metal drip stop roof. This is a fairly new product. I am a little confused on the proper application procedures for a residential home. Your product is wonderful and it is really catching on here in Ohio, I have it installed on my 1976 residential home, but it was installed right over the existing fiberglass shingles with wood purlins. So with that said can you send me any drawings or application procedures your company recommends for new residential home construction and also anything you recommend for installing the drip stop over an existing fiberglass shingle. Feel free to call my business cell to help explain and walk me through the process. I appreciate your time and any installation procedures your team would recommend. MARTIN in OHIO

DEAR MARTIN: Thank you for reaching out to us. Integral Condensation Controls (Dripstop, Condenstop, etc.) are wonderful products. In order to properly function, they do require proper airflow (vented eave soffits and vented ridge, in correct proportions). Installing over a roof deck (either new construction or a reroof) does defeat purpose of preventing condensation (any warm moist air from attic is prevented from contacting underside of cooler roof steel already), however it would still have benefits of reduced sound transmission and decrease in solar heat gain.

 

DEAR POLE BARN GURU: Is it cheaper to build wider rather than longer? How wide can be built without support beams? KRIS in VEEDERSBURG

DEAR KRIS: Ultimately, your most effective interior layout should override saving or spending a few extra cents per square foot. While perfectly square, is typically going to be more cost effective (due to having less wall surface), as long as your length to width ratio is under 3:1 it normally is not going to significantly impact your costs (provided you are not in an extreme wind area, or excessively tall). While I have built clearspan post frame to 100 feet in width (and had engineered designs of 140 feet), price per square foot generally starts to ramp up beyond 80 foot wide. This will, of course, depend upon applicable roof loads.

Post Frame Building Wainscot

Whether your post frame building will be a garage, shop, commercial building or barndominium wainscot an extremely popular option is wainscot.

Roughly 25 years ago I had an 80’ x 150’ x 20’ post frame building erected for my prefabricated wood truss manufacturing business. Whilst a great deal of thought went into this building’s design, there is one crucial element I missed.

Down each long side of our building we placed bollards (read more at: https://www.hansenpolebuildings.com/2018/07/a-real-life-case-for-pole-barn-bollards/ and https://www.hansenpolebuildings.com/2017/05/lifesaving-bollard/) to protect steel siding from units of lumber and forklifts.  As there was no storage across our front wall, we did not place bollards there. A week before we moved in, someone backed a truck into a steel panel directly adjacent to our main entrance door. Of course this steel panel was nearly 30 feet tall, so to replace it would be no small undertaking. Instead of fixing it, I walked in and out of this door and fumed because of this dent! Had I planned appropriately and used wainscot panels, this dented panel could have been replaced in a matter of minutes, saving me untold hours of grief and aggravation!

By common definition, wainscot is an interior wall lower portion whose surface differs from upper wall. Wainscot was borrowed from Middle Low German wagenschot. It is not altogether clear what these origins were, but a generally accepted theory is it is a compound of wagen ‘waggon’ and schot ‘planks, boards’, and it therefore originally meant ‘planks used for making waggons’. Originally it was applied in English to ‘high-grade oak imported from Russia, Germany, and Holland’. This wood was used mainly for paneling rooms, and by 16th century wainscot had come to signify ‘wood paneling’.

Homeowners used to apply wainscoting, especially in dining rooms, to protect walls from damage from chairs and tables. A chair rail atop wainscoting serves as a “bumper,” protecting wall from dings and chips created when a chair or table gets a little too chummy. This wall decoration was often also used to add interest and texture to stairways, while protecting them, too. In fact, it first grew in popularity during Elizabethan times, and it’s quite common in historic English and American Colonial homes.

For post frame (or pole) buildings, wainscot has moved to building exteriors. In simple terms, it utilizes an alternate siding panel to cover approximately three feet of exterior wall lower portions. A most common application, with steel sided buildings, is to use a different color steel panel on the lower wall than the upper. Most often steel wainscot panels are the same color as roofing, however this is certainly not mandatory. This allows for an aesthetic look many find pleasing, while affording an ability to quickly and easily change out a short steel panel, if it would become damaged. This would prove to be a most cost affordable solution and is easier than changing out a full length wall panel.

Alternatively, other materials may be utilized, such as T1-11, cement based sidings, vinyl siding or even stone or brick. Mortarless masonry is a popular wainscot (for extended reading: https://www.hansenpolebuildings.com/2018/10/mortarless-masonry-exterior/).  Pretty much any siding applicable to any other building exterior, can be incorporated as post frame building wainscot. It not only serves a useful purpose, it just plain looks good too.

Building Houses, Siding Options, & Construction

DEAR POLE BARN GURU: Do you build houses from the ground up? ERIC

Hansen Pole Buildings GuesthouseDEAR ERIC: We are not contractors, so we do not build anything for anyone anywhere. Our post frame building homes are designed for the average person who can and will read instructions to successfully construct their own home – even without the help of a contractor! We will design specifically to meet with the requirements of your site and your needs and budget in mind. Our system provides the structure – what holds your house up, allowing you to place interior non-load bearing walls anywhere your heart fancies. We can design for full or partial basements, concrete slab on grade or crawlspace applications. Homes may be on a single level, or multiple levels up to and including three stories above grade.

Basically – if you can dream it, we can design and provide it.

DEAR POLE BARN GURU: I need to know what type of wood the board and batton siding is.  Cedar?  What kind of cedar?  I can’t find specifics on the materials list or my project site.  Thanks. TRISHA in MEAD

Hansen Buildings TaglineDEAR TRISHA: The rough sawn T1-11 panels are typically either a Southern Yellow Pine or Douglas Fir facing. The 1x for battons and corners is most usually Western Red Cedar.

 

DEAR POLE BARN GURU: I am buying a timber frame barn kit. Can you erect this building and contract the construction? STEPHEN in MIDDLETOWN

DEAR STEPHEN: We provide post frame (pole building) custom designed kit packages. We are not contractors in any state, so no – we cannot erect your building or contract the construction.
